Abstract
The comprehension of the phenomena related to magnetism allowed advances in various fields of knowledge and several modern applications that are now part of our daily lives. Specifically, the magnetic nanoparticles (NPs) has aroused a great interest among researchers in recent decades. This curiosity due to its unique properties is due to its small size and surface interactions. One of the main physical phenomena that appear when we reduce the size of a magnetic particle is called superparamagnetism. In this work, we have looked for a description and understanding of the mathematical formalism attached to magnetic phenomena at nanoscale through the application of the Langevin’s function to magnetic NPs in superparamagnetic regime and non-interacting model. Accordingly, we use theoretical simulations of magnetization curves as a function of applied field to study some parameters and verify its compatibility with magnetic characterization data obtained for samples of NPs magnetite and maghemite. In this way, we can get relevant information to the analysis of the magnetic behavior of nanoparticulate systems. Finally, we have lunched the potential of these magnetic NPs in biomedical applications both in diagnostic techniques and in disease treatments.
